Abstract: A nail polish bottle comprises a bottle body, a cap including a disc portion having a center hole and one or more air holes and including a discharge passage and one or more external-air introduction grooves in flow contact with the air holes. A pressure opening and closing valve is mounted to the disc portion such that a skirt portion of the valve may sit below the disc portion and a top of the valve may be above the disc portion. The skirt portion may press against the disc portion to close the air holes. When internal pressure in the bottle body opens the top of the valve, nail polish may flow through the discharge passage if the bottle is upside-down. When the internal pressure is released, the top of the valve may close and the skirt portion may move away from the disc to open the air holes.

Abstract: Disclosed are a system, apparatus, and method for 3D object segmentation within an environment. Image frames are obtained from one or more depth cameras or at different times and planar segments are extracted from data obtained from the image frames. Candidate segments that comprise a non-planar object surface are identified from the extracted planar segments. In one aspect, certain extracted planar segments are identified as comprising a non-planar object surface, and are referred to as candidate segments. Confidence of preexisting candidate segments are adjusted in response to determining correspondence with a candidate segment. In one aspect, one or more preexisting candidate segments are determined to comprise a surface of a preexisting non-planar object hypothesis. Confidence in the non-planar object hypothesis is updated in response to determining correspondence with a candidate segment.
